This spec is a proposition for a voting protocol over Waku V2.
|
||
|
|
|
||
|
|
# Motivation
|
||
|
|
|
||
|
|
In open p2p protocol there is an issue with voting off-chain as there is much room for malicious peers to only include votes that support their case when submitting votes to chain.
|
||
|
|
|
||
|
|
Proposed solution is to aggregate votes over waku and allow users to submit votes to smart contract that aren't already submitted.
|
||
|
|
|
||
|
|
# Smart contract
|
||
|
|
|
||
|
|
Voting should be finalized on chain so that the finished vote is immutable.
|
||
|
|
Because of that, smart contract needs to be deployed.
|
||
|
|
When votes are submitted smart contract has to verify what votes are properly signed and that sender has correct amount of SNT.
|
||
|
|
When Vote is verified the amount of SNT voted on specific topic by specific sender is saved on chain.
|
||
|
|
|
||
|
|
## Double voting
|
||
|
|
|
||
|
|
Smart contract should also keep a list of all signatures so that no one can send the same vote twice.
|
||
|
|
Another possibility is to allow each sender to only vote once.
|
||
|
|
|
||
|
|
## Initializing Vote
|
||
|
|
|
||
|
|
When someone wants to initialize vote he has to send a transaction to smart contract that will create a new voting session.
|
||
|
|
When initializing a user has to specify type of vote (Addition, Deletion), amount of his initial SNT to submit and public key of community under vote.
|
||
|
|
Smart contract will return a ID which is identifier of voting session.
|
||
|
|
Also there will be function on Smart Contract that when given community public key it will return voting session ID or undefined if community isn't under vote.
|
||
|
|
|
||
|
|

||
|
|
|

|
|
## Sending votes
|
||
|
|
|
||
|
|
Sending votes is simple every peer is able to send a message to Waku topic specific to given application:
|
||
|
|
```
|
||
|
|
/status-community-directory-curation-vote/1/{voting-session-id}/json
|
||
|
|
```
|
||
|
|
|
||
|
|
vote object that is sent over waku should contain information about:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
type Vote = {
|
||
|
|
sender: string // address of the sender
|
||
|
|
vote: string // vote sent eg. 'yes' 'no'
|
||
|
|
sntAmount: BigNumber //number of snt cast on vote
|
||
|
|
sign: string // cryptographic signature of a transaction (signed fields: sender,vote,sntAmount,nonce,sessionID)
|
||
|
|
nonce: number // number of votes cast from this address on current vote (only if we allow multiple votes from the same sender)
|
||
|
|
sessionID: number // ID of voting session
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Aggregating votes
|
||
|
|
|
||
|
|
Every peer that is opening specific voting session will listen to votes sent over p2p network, and aggregate them for a single transaction to chain.
|
||
|
|
|
||
|
|
## Submitting to chain
|
||
|
|
|
||
|
|
Every peer that has aggregated at least one vote will be able to send them to smart contract.
|
||
|
|
When someone votes he will aggregate his own vote and will be able to immediately send it.
|
||
|
|
|
||
|
|
Peer doesn't need to vote to be able to submit the votes to the chain.
|
||
|
|
|
||
|
|
Smart contract needs to verify that all votes are valid (eg. all senders had enough SNT, all votes are correctly signed) and that votes aren't duplicated on smart contract.
|
||
|
|
|
||
|
|
## Finalizing
|
||
|
|
|
||
|
|
Once the vote deadline has expired, the smart contract will not accept votes anymore.
|
||
|
|
Also directory will be updated according to vote results (community added to directory, removed etc.)
